This equipment includes a mounting plate that integrates a main board, oil level indicator, pressure gauge, printer, and other functional devices; the ease of maintenance and safety are paramount. Currently, to protect the mounting plate from external environmental influences, the chassis is usually equipped with a protective cover.

[0003] However, traditional chassis protective covers are often fixed to the chassis or require complete disassembly. With this connection structure, when the mounting plate needs maintenance, technicians must completely remove the protective cover from the chassis. This involves disassembling numerous screws, clips, and other fixing components, making the process lengthy, complex, and time-consuming. Furthermore, the completely removed protective cover is prone to being lost, leaving the mounting plate exposed. During the replacement or reinstallation of the protective cover, there is a risk of damage to the mounting plate due to collisions or scratches. Utility Model Content

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] This utility model provides, for example Figure 1-7 The transmission maintenance equipment shown includes: a housing 1; a mounting plate 2, which is installed on the top of the housing 1; and a rotation protection device 3, which is installed on the housing 1 and can rotate relative to the housing 1 on a fixed axis to cover the mounting plate 2.

[0044] The mounting plate 2 can be a single plate or multiple plates, used to support some functional devices 23 of the gearbox maintenance equipment. The functional devices 23 can be a main board, oil sight glass, pressure gauge, printer, etc. The rotation protection device 3 covers the mounting plate 2 when not under maintenance, so as to protect the mounting plate 2 and the functional devices 23.

[0045] The rotation protection device 3 includes: a support mechanism 31, which is fixedly installed inside the chassis 1 and is fixed in position relative to the mounting plate 2; and a protective cover 32, which is rotatably connected to the support mechanism 31 and is connected to the mounting plate 2 through a quick-release structure. The quick-release structure includes a screw connector and a screw hole on the mounting plate 2. The screw connector passes through the protective cover 32 and is screwed into the screw hole. That is, the protective cover 32 is connected to the mounting plate 2 by screws. During maintenance, it is only necessary to remove the fixing screws on the protective cover 32, rotate and flip the protective cover 32 until the protective cover 32 rotates to the anti-rotation position that contacts the anti-rotation post 313. It is not necessary to completely remove the protective cover 32 to maintain the mounting plate 2. It is convenient and reliable. Compared with the traditional method that requires complete removal of the protective cover 32, in terms of safety, the protective cover 32 does not need to be completely removed. During the maintenance process, the support mechanism 31 always maintains the rotational connection with the chassis 1, which not only avoids the risk of loss of the protective cover 32, but also continuously provides a certain degree of protection for the mounting plate 2, effectively preventing damage to the mounting plate 2 due to collision and scratch.

[0046] Furthermore, the protective cover plate 32 is provided with multiple functional device clearance holes 33; the mounting plate 2 is provided with multiple functional devices 23. When the protective cover plate 32 covers the mounting plate 2, the multiple functional devices 23 correspond to the multiple functional device clearance holes 33 respectively, which can prevent the protective cover plate 32 from hitting the functional devices 23 on the mounting plate 2, and also avoid affecting the user's observation or operation of the functional devices 23.

[0047] Furthermore, a flipping device can be provided on the protective cover 32. The flipping device can be a lightweight device with fewer connecting wires that can flip along with the protective cover 32 when it is flipped, such as a display screen, thereby reducing the installation load on the mounting plate 2 and effectively planning the installation space of the components.

[0048] Furthermore, the mounting plate 2 may have an avoidance opening facing the flipping device to allow the flipping device to pass. When the protective cover 32 covers the mounting plate 2, the avoidance opening prevents the mounting plate 2 from impacting the flipping device. Moreover, since the avoidance opening connects the back of the mounting plate 2 and the inside of the chassis 1, when one side of the protective cover 32 is flipped away from the mounting plate 2, maintenance personnel can also inspect the back of the functional device 23 and other components inside the chassis 1 through the avoidance opening, effectively improving the convenience of maintenance.

[0049] In some embodiments, the gearbox maintenance equipment may further include a protective component disposed on the front of the mounting plate 2, the front of the protective cover 32, and / or the back of the protective cover 32. The protective component may be a silicone protective pad, etc. When the protective cover 32 is flipped, the protective component provides cushioning protection for the mounting plate 2 and / or the protective cover 32.

[0050] The support mechanism 31 includes: a support frame 311, which is fixedly installed inside the chassis 1; a rotation positioning component 312, which is installed on top of the support frame 311 and is used to limit the fixed-axis rotation of the protective cover 32; and an anti-rotation post 313, which is fixedly installed on the support frame 311 and located below the rotation positioning component 312. The support frame 311 is fixedly installed at the corner of the chassis 1 to facilitate the shaping and support of the chassis 1, making the use of the chassis 1 more stable. The rotation positioning component 312 helps to limit the rotation of the protective cover 32, making the fixed-axis rotation of the protective cover 32 more stable. The anti-rotation post 313 helps to stop the rotation of the protective cover 32 at its extreme position, so that when the ear plate 321 rotates to the state of contact with the anti-rotation post 313, it is in the anti-rotation position to prevent the protective cover 32 from rotating excessively.

[0051] The rotary positioning assembly 312 includes: an internally threaded cylinder 3121, which is fixedly installed on the support frame 311; a lug 321 is connected to the bottom of the protective cover 32, and the lug 321 is rotatably engaged with the internally threaded cylinder 3121; and a positioning screw 3122, which is threadedly engaged with the internally threaded cylinder 3121. The internally threaded cylinder 3121 is cylindrical, which allows the lug 321 to rotate around its axis, making the flipping of the protective cover 32 more stable. The threaded engagement between the positioning screw 3122 and the internally threaded cylinder 3121 facilitates the installation of the positioning screw 3122, so that the head of the positioning screw 3122 can limit the rotation of the lug 321 and prevent the lug 321 from falling off.

[0052] Furthermore, a buffer element can be fitted onto the internally threaded cylinder 3121. The buffer element can be located on both sides of the ear plate 321, or it can be fitted between the wall surface of the ear plate 321 and the cylinder wall surface of the internally threaded cylinder 3121. Thus, when the ear plate 321 rotates, the buffer element plays a buffering role, preventing the protective cover plate 32 from rotating too fast and impacting other parts.

[0053] Furthermore, the ear plate 321 has a stop on the side near the anti-rotation post 313. When the protective cover plate 32 rotates away from the mounting plate 2 at a certain angle, the stop will abut against the anti-rotation post 313, thereby preventing the protective cover plate 32 from rotating excessively. In addition, a protective pad can be provided on the stop to prevent the stop from directly impacting the anti-rotation post 313.

[0054] Furthermore, the gearbox maintenance equipment may also include a directional structure for orienting the flipping of the protective cover 32. In some preferred embodiments, the directional structure may be an annular groove provided along the wall of the internally threaded cylinder 3121, which is adapted to the ear plate 321. When the protective cover 32 is flipped, the wall of the annular groove abuts against the ear plate 321, thereby orienting the flipping of the protective cover 32. In addition, an angle adjustment structure may also be provided between the wall of the annular groove and the ear plate 321, such as a locking block provided on the ear plate and a locking groove provided at equal intervals along the bottom surface of the annular groove, which can fix the protective cover 32 at a certain angle when it is flipped and provide a certain buffering effect for the flipping.

[0055] The mounting plate 2 has an outer edge 21. The mounting plate 2 can be installed along the top of the chassis 1. The edge 21 can be bent and installed on at least one side of the mounting plate 2. The edge 21 can be attached to or removed from the side of the chassis 1, thus enabling quick installation and removal of the mounting plate 2. Specifically, the connection between the edge 21 and the chassis 1 can be achieved through screws or snap-fit ​​structures.

[0056] Furthermore, the protective cover plate 32 is provided with a protrusion 322, and an elastic pre-positioning mechanism 22 is installed on the inner side of the edging 21. The elastic pre-positioning mechanism 22 is used to pre-position the protrusion 322. When the protective cover plate 32 is flipped over to cover the surface of the mounting plate 2, the elastic pre-positioning mechanism 22 is locked on the inner side of the protrusion 322 to pre-position it so that the screws can be tightened. This enables the subsequent installation and fixation of the protective cover plate 32 by the screws, making the position of the protective cover plate 32 more stable.

[0057] Furthermore, the elastic pre-positioning mechanism 22 includes: a connecting plate 221, which is disposed on the inner side of the edging 21; a pre-positioning block 222, which is mounted on the connecting plate 221 and is used to position the protrusion 322; a guide post 223, one end of which is connected to the connecting plate 221, and the other end of which is provided with a spring pin; a spring 224, which is movably sleeved on the outside of the guide post 223; a mounting bracket 225, which is slidably engaged with the end of the guide post 223; and a fixing member 226, which is used to fix the mounting bracket 225 on the inner side of the edging 21. The fixing member 226 facilitates the fixing of the mounting bracket 225 on the edging 21 and limits the sliding movement of the guide post 223, thereby making the linear movement of the connecting plate 221 more precise. To enhance stability, the spring pin is inserted into the end of the guide post 223, which facilitates the limiting of the insertion between the guide post 223 and the mounting bracket 225, preventing the guide post 223 from disengaging from the insertion between the mounting bracket 225. The compression deformation of the spring 224 facilitates the elastic support of the connecting plate 221, allowing the prepositioning block 222 to be elastically locked inside the protrusion 322, thus prepositioning the protective cover 32. When the protective cover 32 is flipped towards the mounting plate 2, the protective cover 32 will contact the inclined surface at the top of the prepositioning block 222. Through the force component, the prepositioning block 222 is pressed and moved towards the mounting bracket 225 until the protrusion 322 passes through. At this time, the protective cover 32 covers the mounting plate 2, and the bottom of the prepositioning block 222 is locked inside the protrusion 322, thus achieving the prepositioning of the protective cover 32.

[0058] In one embodiment, the chassis 1 includes a back panel (not shown) with ventilation holes. The ventilation holes allow for the rapid dissipation of heat generated by the gearbox maintenance equipment during operation.

[0059] In one implementation, a winch frame 12 is provided on one side panel of the chassis 1 for winding the oil inlet pipe 13 and the oil outlet pipe 14 of the transmission maintenance equipment. The winch frame 12 facilitates the storage of the oil inlet pipe 13 and the oil outlet pipe 14, reducing the space occupied by the scattered placement of the oil inlet pipe 13 and the oil outlet pipe 14. Furthermore, an active suction pipe 15 is also wound on the winch frame 12. This active suction pipe 15 is used to connect to the pump circulation system inside the automatic transmission fluid cleaning and changing machine, for actively sucking up excess transmission fluid from the vehicle's transmission and guiding the sucked transmission fluid into the old oil tank inside the automatic transmission fluid cleaning and changing machine.

[0060] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
